Mayan Astrology (Tzolkin)

The Tzolk'in (in modern transcription Cholq'ij, "count of days") is the sacred ritual calendar of the Maya, with no direct astronomical counterpart: its 260 days correspond to neither the lunar nor the solar cycle.

The riddle of 260. The origin remains debated. Theories:

• The period of human gestation
• The synodic cycle of Venus
• Mathematical combinatorial principles

Antiquity. The Tzolk'in existed in pre-Columbian Mesoamerica from at least the first millennium BCE.

Structure — Intersection of Two Cycles

• 20 solar signs — called nawales or day signs
• 13 tones — vibrations

The birth kin. The combination of sign and tone falling on a person's birthday forms their "kin" — the fundamental energetic imprint.

20 Signs and 13 Tones

Signs. Imix, Ik', Ak'bal, K'an, and so on — associated with natural forces, deities, and qualities of consciousness.

Tones. Define the quality of intention:

• Tone 1 — magnetic attraction
• Tone 13 — cosmic completion

Modern Practice vs Tradition

Not what the ajq'ijab' did. Contemporary Mayan astrology differs considerably from what the priest-astrologers (ajq'ijab') actually did: it has passed through several layers of interpretation.

Dreamspell vs tradition. Including the influence of Dreamspell by José Argüelles (#48), which some practitioners conflate with the traditional Tzolk'in. Academic Mayanists draw a clear boundary between the two.

Place in Errarium

Mesoamerican tradition. In Errarium, Mayan astrology represents the Mesoamerican symbolic tradition as an independent system with a unique number-rhythm that cannot be reduced to others.

Uniqueness of the 260-day structure. The Tzolk'in's uniqueness lies in the 260-day structure as a self-contained model of time.
